ENGINE.

' Application filed August 31, 1921. Serial No. 497,216.

To all whom it may concern:

Be it known that I, EDWARD Gr. GOULD, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Engines, of which the following is a specification.

This invention relates to an engine, and especially to an internal combustion engine of the rotary cylinder type.

One of the objects of the present invention is to generally improve and simplify en ines of the character described, and especially to provide a structure which will permit a minimum of parts,'light weight horse power and a high efficient turning torque.

- Another object of the invention is to pro-- vide a structure which will require .a minimum of vertical space and which will permit accessibility for adjustment, inspection, repairs, etc.

Another object of the invention is to provide an engine comprising two cylinders preferably horizontally disposed and arranged inline formation; a double acting piston in each cylinder, a rod connecting the the reciprocal same, means actuated b movement of the pistons or transmtting a revolving movement to the pistons and cylinders in unison about their longitudinal axis, and further to provide a'novel rotary valve mechanism whereby the gases may be admitted, ignited and exhausted.

Other objects will hereinafter appear.

The invention cons'sts of the parts and the construction, combination and arrangement of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in whic h.

Fig. 1 is a central, vertlcal, longitudinal section through the engine.

Fig. 2 is a'plan view of the same.

Fig. 3 is an enlarged cross section on line 33, Fig. 1.

Fig. 4 is a diagrammatic view showing the different positions assumed by the rotary valve mechanism.

Fig. 5 is an enlarged cross section on line 5-5, Fig. 1. g

Fig. 6 is a diagram for the formation" of the annular cam groove;

Referring to the drawings in detail, and

particularly to Figs. 1 and 2, A and B indi-' cate a. air of cylinders which are horizontally disposed and arranged in line formation. The cylinders are closed at their respective ends by head members such as indicated at 2, 3, 4, and 5, and each cylinder is provided with a piston 6, which pistons are connected by a common rod 7 the rods passing through the heads 3 and 4, and suitable stuffing boxes not here shown may be provided.

The heads employed are, practically speaking, identical in formation. They are 9, which are supported by journal members 10 and 11. The heads 3 and at are similarly provided with extensions 12 and 13, Sup ported by journal members 14 and 15, and they are further extended to" permit the cylinders to be connected by means of a cross head generally indicated at O. The engine as a wholeis supported by a main frame D (see Fig. 2) the respective journals 10, 11,, i

14 and 15, being supported thereby and secured thereto. as a. support for a series of manifolds, indi- ,cated at 16, 17, 18 and 19, respectively, and it further forms a support for a cam housing generall indicated at E. The manifolds just referre to are identical in construction and are clearly illustrated in 3. Each manifold is provided with three ports or passages as indicated at 20, 21 and 22. These ports are so positioned as to align with the ports 8 in the respective cylinder heads. The ports 20 are all connected with an exhaust manifold 23; the ports 21 with an inlet manifold 24, and the orts 22 each serve asa support for a sparkp ug 25.

The cylinders, the heads secured at-each end thereof, the pistons reciprocally mounted in the respective cylinders, and the common rods :7, connecting the same, are all adapted to rotate during the operation of the engine. This is accomplished in the following manner:

Secured on the rods 7, within the cam housing E, is a cross arm 26. Secured within the cam housing are two cam members 27 and 28, which are sufficiently separated to form an annular cam roove 29, having a shape or formation su stantially such as The main frame also serves shown in Fig. 6. Mounted on each end of the cross arm 26 is'a roller 30, which is adapted to engage ,the opposite cams 27 and 28, and adapted to rotate in unison with the cross arm 26 is a cross head C, which is attached, as previously stated,,at its opposite ends to the cylinder head extensions 12-and 13. The cross head C consists of a pair of arms 31 and 32, which are. secured at their inner ends to the extensions 12 and 13. The

outer ends of the arms 31'and 32 are connected by longitudinal bars 33 and these in turn are longitudinally'slotted as at 34 to permit the end of the cross arm 26 to extend therethrough. Therefore if a re the heads 3 and 4, which are attached to the respective cylinders, as a driving connection is formed between the arm 26 and the cross head C, due to the fact that arm 26 passes.

through the longitudinal slots formed in the connecting bars 33 of the cross head. Hence a reciprocal movement will not only be transmitted to the pistons during the operation of the engine, butv a turning movement" will,simultaneously be transmitted,

the heads, the cross head and the cross arm 26, to rotate in unison about their longitudinal axis. The heads are as previously stated surrounded by the tationary manifolds 16,

17, 18 and 19, and the ports 8 formed in the respective heads will therefore alternately register with the inlet. and exhaust ports formed in the manifold, and also with the 5 spark plugs 25.

During the rotation of the cylinders, gas will alternately admitted to opposite ends of the cylinders, compressed, ignited and finally exhausted, and one impulse will be nnparted during each quarter of a revolution of thecylinde'rs due to the fact that the annular cam groove 29, formed betweenthe cams 27 and'28, has two rises and two depressions formed therein as indicated at 40 and 41, respectively. In other words two complete reciprocations are imparted to the pistons during each revolution and hence an impulse or working stroke is imparted once durin each one-fourth revolution,-

thereby p ucingv a. highly eflicient turning torque.

In an engine constructed as here illustrated, it is exceedingly compact and simple, a of parts'is employed due to the fact that mechanically-actuated valves are entirely eliminated. In fact the heads ofthereby causing the pistons, the cylinders,-

character described, spaced the respective cylinders, in cooperation with the-stationar manifolds, serve the function of valves -w ereby the gases are admitted and exhausted. The engine may furthermore be air cooled due to the fact that the cylinders rotate, and the ribs, such as indi-' rated at 50, may be formed on their exterior surfaces. Power may be transmitted by forming a pulley on the exterior surface of one or both cylinders, or a coupling such as. shown at 51 may be formed on the ex-- tension 9. Another feature of the present invention is that the vertical space consumed.

by the engine is reduced to a minimum, hence producing an-ideal structure for aeroplane work or the like as head on or air resistance is exceedingly minimized when comparison is niade'with standard types of motors now employed. Another feature of the invention is accessibility. All parts are separated due to the arrangement provided, thereby permitting inspection, adjustments, and repairs,.and lubrication can easily beaccomplishcd and independently taken care of as the cylinders areseparated and form independent units, and similarly the cam housing, which may be filled with ordinary transmission case grease or the like. Another important feature is the construction of the annular cam whereby rotary movement is transmitted. This cam is made in two sections and independently secured by keys or the like, such as illustrated at 60, which are interposed between the cams and the cam housing. Longitudinal adjustment 15 therefore permitted between the cams, thus taking care of all wear which may take place.

Another important feature is the cone shaped formation of the cylinder heads. This is important as it permitsa leak-proof running fit to be readily malntamed between the heads and the stationary manlfolds surrounding the same.

While the engine is here described as an internal combustion engine, it is obvious that the inlet manifolds might be connected with a source of steam or air supply, and that the engine will be equally operable in either instance. -I stood that various changes in form and proportion may be resorted to w 1th1n the scope of the appended "claims, similarly that the materials and finish of the several arts emloyed maybe such as the experience and udgm ent of the manufacturer may dictate [or varying uses may demand.
